Just wanted to update. Made the brisket fat side down with water in the pan, ran the temps consistently in the low 200's and took off after 11 hours when it hit 200. Didn't trim either and used KK's coffee-cocoa rub. Held in a dry cooler for several hours waiting for company to arrive. Results were good, not great. A little dry on the thin end and less of a smoke ring than I would have expected. I used MM, filled the charcoal ring full with Kingsford comp, dropped a full chimney of lit on top and lined the perimeter of the ring with 7 pieces of wood per Harry Soo's advice. I served with NO. 5 sauce which was great, especially with the addition of the coffee-cocoa rub which totally changed the flavor from when I've made it before. A wonderful, versatile sauce.
I'd like to try HH but time would not allow that on this cook. Next time I will foil at 165 and maybe add some liquid and seasonings to the foil.
Thanks again for all the feedback.
